[Ageneses of the gallbladder: revision of the literature and a case reported].

BACKGROUND

ageneses of the gallblander (AGB) is an infrequent congenital malformation. It was described by Lemery in 1701, for the first time. Until today, it has been described 400 cases worldwide. The objective was to present a case of AGB and review the literature.

CLINICAL CASE: female of 61 years who was attended for relating colic pain, intensive and persistent in right upper abdomen during two days, accompanied of heartburn and nausea; relaxed abdomen with light pain to deep palpation in right abdomen, without peritoneal irritability. The lab showed Hb 12,8 g/dL, Hct. 40,04 %, WBC 5090/mL, PlT 266000 mL, direct bilirubin 0.3 mg/dL, bilirubin indirect 0.5 mg/dL, PT 7.4 g/dL, ALB 4 g/dL, glucose 107 md/dL, urea 36 md/dL. Abdominal echography showed intrahepatic and extrahepatic bilary tract without evidence of dilation, and partially identified gallbladder. The diagnosis of gallbladder agenesis was established by cholangiography.

CONCLUSIONS

the case presented symptoms specific of gallbladder disease without blockage of the liver as it is described in the literature. The cholangiography and CT revealed absence of gallbladder disease and corroborated diagnosis of vesicular agenesis.
